Instantaneous application of heat in hard glassy matrices induced by electromagnetic wave or radiation can trigger the formation of nano-sized balloon structure. The starting hard matrix was prepared by the sol-gel method since that method is advantageous to render a quite slight amount of low-molecular-weight species remain in the hardened matrix. In this process, low-molecular-weight species forms gaseous species that displace the surrounding hard matrix in an isotropic geometry. As a result of that, isotropic spherical voids are ubiquitously yielded. The most marked feature of those structures is that they tend to remain as small as 100 nm at most, which indicates the suppression of the mutual coalescence of those balloon-like structures. An auxiliary work is ongoing to process those materials with the nano-sized spherical voids into fine powder. The features of the obtained powders are preliminarily investigated form those kinematical behavior.

通过电磁波或辐射在硬质玻璃基质中瞬时施加热可以触发纳米尺寸的气球结构的形成。通过溶胶-凝胶法制备起始硬基质，因为该方法有利于使相当少量的低分子量物质保留在硬化基质中。在此过程中，低分子量物质形成气态物质，其以各向同性几何形状置换周围的硬基质。其结果是，各向同性的球形空隙无处不在。这些结构的最显著特征是它们倾向于保持最多100 nm的小，这表明这些气球状结构的相互聚结受到抑制。一项辅助工作正在进行中，以将这些具有纳米尺寸球形空隙的材料加工成细粉。从这些运动学行为初步探讨了所得粉末的特征。
